To all whom itjmay concern;

Be it known that I, M. LANE, a citizen. of the United States, and aresident of the city of St.- Louis. and State of- Missou'ri, haveinvented a new and "useful Im proveinent in -Metal: vVe'ather Stri ps,of.-

inetal and applied to' wooden frames, and

sashes, It has for its" principal nbjects to'.

prevent; binding and insure an ;easyi,-inoyement ofthe'sashwhenit'swells andjshrinksf" .due to climatic changes;and attaincertain other advantages h more fully f appearing,

' 1 In the drawings, .a portion of an ordinary 7 window frame'lis'sh'o'wn as arranged for a i slidingsash .2. ,The innervertical'corner portion of the sash adjacentto the parting strip 3 is rabbeted,as at 4-, to make room for the beaded groove-portion 5'of-arigid metalWeatherstrip member 6. -This strip or memher 6 has it's beadedgrooveportion oflset I inwardly, as at 7, from its-marginal portion 8which is tacked or'otherwise fastened to I the sash. f The sashispreferably rabbeted slightly also adjacent to said first-mentionedrabbeted portion, so that the secured portion of the strip liesflushwi'th' the face of the sash. i

The coiiperating Weatherstrip member 9 isrelatively'flexlble andpreferably resilient.

It is secured along one marginal portionto the "window frame, as": at 10,' pre ferably Patented Mar. 13,1917.

under the stop memberor molding 11;? This 'flexible or resilientstrip 9is-bent substanjf;

tial-ly' at right angles adjacent to its'op p site margin, as at 12, andthen rebent' o'rf' v1ooped, 'a's at 13, to provide a substantially "6o,

On the otherhand, should the back in the I direction of the window'frame.

:w'hich works in the groove 15. It is noted that the grooved portion 5of the comparatively rigid strip 6 andthe rib portion of the relativelyflexible strip 9 are, in effect,

edge. portions of the metal strips formed into U-shape,and that theU-shap'e portion which c'onstitutes therib is smaller than the otherU-shape portion that constitutes the I groove, and that the two U-shapeportions stand out at right angles to the adjacent portions of theirrespective strips. It is fur.- th er noted.that the outer surface of therib. is'jconvex' and that the inner surface-of the grooveis-concaye and.that the contact between the two surfaces is-limited tofthe baseportion.
